SLITTING AND 'WINDING MACHINE.

Specification of Letters Patent. Application iilad August 3f 1907.4 Serial No. 386.891.

Patented Dec. .'17, 1907.-

To all whom it may concerni Be it known that I, HENRY citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Slitting and Winding Machines, of which the following is a specification.

It is the object of my invention to provide an improved slitting -and winding machine in which the sheet to be slitted and wound is introduced between cutters for slitting the sheet into lengths of suitable widths, the sheet being drawn throu h the cutters by suitable drawing-rollers closely adjacent to the cutters, and wherein the strips may be wound in separated relation by suitable winding mechanism acting upon the combined strips from the center of the rolls being wound and also selectivel upon the surfaces of said separated rolls, or subjecting said separated rolls to combined rolling action from the center and also to separated rolling action at their peripheries, whereby the main duty of the winding function is accomplished from the center and auxiliary differential winding action is imparted to the se arated strip-rolls at their surfaces, so that a l of the strip-units may be compactly rolled irrespective of differences in condition or thickness of material.

M im roved device is especially ap licable or slitting and rewindin -various inds of apers, whether plain, oile or waxed.

n waxed papers an objection has hereto' fore been that the wax collected on the surj face of the rollers, and another objection has been,in the manipulation of various kinds of pa ers, that electricity was generated, resu ting in magnetism retarding or preventing release between the paper and rollers, the tendency having been for the paper to follow the peripheries of the rollers in their rotation. I prevent these objections by making one of the drawing rollers of say iron or similar substance, and providing a scraper for scraping the surface of the wax that may accumulate thereon, and in providing the surface of the other roller with an electrically non-conducting covering, such as felt, thereby relieving the tendency of the paper to cling to the surface of said rollers in their rotation. Y

The invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

P. HILBERT, a

Figure 1 represents. a `side elevation of my improved device, partly broken away. Fig. 2 is a plan-view of the same. Fig. 3 is a perspective view of the winding end of the mac 'ne, partly broken away. Fig. 4; is a ,perspective view of one of the tubes for the surface-winding roller; and Fig. 5 is a similar view of one of the separating washers for the same.

1 represents the frame embracin the sides 3 4 tied together by suitable tie-ro s 5 5.

6 is a shaft arran ed to support the unwinding rollv7 and he d in releasable bearings 8, proper or usual means being provided for properly braking the roll 7 or lts shaft for placin 'the pro er tension upon ,the web 9 whi h is adapte to be unrolled from the roll 7 and pass through the slitting mechanism for being slit into strips, the strips being then se arated and rewound u o n a rewinding ro l. The shaft 6 has a col ar 10 fast thereon. A friction-band 11 is received about this collar, aset-screw 12, passing through ears 13, adjusting the frictional resistance thereof. The band 11 is arranged to strike pins 14 on the frame for arresting the rotation ofthe band and ap lyin the frictional resistance thereof to t e colar. The collar has an annular groove 15 which receives a vyoke 16 ofthe bell-crank lever 17 privoted von a bolt 18 to a bracket 19-on the ame, a screw-rod 20 threading into aswivelnut 21 on the lever. The screw-rod is suitably journaled in the frame and extends to the delivery end of the machine, where it is provided with a hand-wheel 22 for its manipulation.

23 24 and 25 are suitable tension and smoothing rollers for the'web and are adapted to run idle and to have more or less resistance applied thereto in suitable manner, not particularly described because wellknown.

26 27 are knife-shafts journaled at their ends respectively in boxes 28 supported in slide-ways 29. These shafts respectively have knives 32 33 adjustably secured thereto in such manner that' the knives may be positioned lengthwise of the shafts for cutting the web'into strips of suitable widths.

37 38 are thedrawing-rollers andare positioned closely adjacent the cutters for drawing the paper through the cutters, the eHeot being that the drawing action takes place only upon' a short length of the cut strips, thereby minimizing the danger of tearing 'the strips. The drawing-roller 38 has a shaft 39 journaled in boxes 40 supported in the slideways 41 of the housing 42. This roller is preferably a metal roller, for` instance iron, against the periphery of which a scra er 43 acts to scrapeV the wax which may e received upon the roller from the paper, so as to kee the roller clean. This scraper is prefera ly secured to a rock-shaft 44 in bearings 45 on the housing, the scraping edge be` ing an eccentric journal 55 journaled in a.

bearing-block 56 secured to the upper end of the housing. At its outer end the vshaft 54 has a hand-wheel 57 for turning the shaft and thereby raising or lowering the boxes for adjusting the elevation of the drawing-roller 37. After adjustment the shaft mayl be clamped in adjusted position by the setscrew 58. This roller 37 has a covering 59 of electrically non-conducting material, such as felt, so that in the operation of' the machine j magnetism may not be created or induced between the drawing-rollers, and insuring that the aper-strips shall readily release from the diawing-rollers to prevent tearing of the same. The cut strips are then directed about the rollers 60 61, the roller 61 being journaled at the upper ends of arms 62 extending upwardly from the housing. The strips are further directed about the rollers 63 64 and are then wound about the windingarbor 65, for forming the rewinding roll 66, but prior to reaching theroller 63 a separator-roller 67 is caused to act upon the strips in the stretch between the roller 61 and the roller 63 for separating the strips so that they may be wound about the winding-shaft or arbor in separated relation for forming distinct rolls 68 of narrow strips which may be readily removed without the necessity of chopping them apart 'when removing them and lnsuring that the rolled strips may be unwound without having the edges of the strips crushed or mingling with each other.

The separator-roller 67 referably comprises short sections 70 of tubes separated by Washers 71 of greater diameter than the tubes and suitably positioned end for end upon the shaft as by collars 72. The tubes and washers are preferably of metal and sufficiently loose upon the shaft to permit their turning upon the shaft if undue stress or 4friction be applied at their peripheries.

The winding-shaft is arranged to be suitably driven as will be hereinafter more particularly explained, for acting collectively -96 on a bracket 97 on the frame.

ing roller 76 is also provided. This surface- A winding roller, similarly to the separatorroller 67, acts'as a separator-roller, being similarly constructed, as by being provided with separator-tubes V77 having washers 78 therebetween suitably positioned similar to the tubes and washers of the separator-roller 67 as by collars 79, the tubes and washers being sufficiently loose upon the 'shaft to permit their turning upon the shaft if undue stress or friction be exerted at their eripheries. Separator tubes of different' engths may be provided for strips of diderent widths. I

The, driving mechanism of my improved device will now be described. A primemover is shown as a` pulley 81 which rotates loosely on a stud 82 secured to the frame and forms one member of afriction-clutch 83, the other member 84 of which also rotates loosely about the stud 82 and hasr a pinion 85 thereon. 86 is a collar, also on the stud 82. A lever 87 has a fork 88 taking about the collar and is articulated with the collar by pins 89. The lever 87 is pivoted at 90 on a bracket 91 and has a threaded nut 92 swiveled thereon, an adjusting screw 94 being threaded into said nut 92 and having a handle 95, for positioning the lever 87 and controlling the frictional engagement in the clutch 83, the adjusting screw 94 being journaled in bearings There is a ball-bearing 98 between the collar 86 and the pulley 81 and a ball-bearin 99 between the clutch-member 84 and the ame of the machine. The friction-clutch 83 forms the initial-drive for the machine. There is a second friction-clutch 101, which is a driven friction-clutch, and is operated from the friction-clutch 83 and has for its purpose the operation of the central winding-shaft. The friction-clutch 101 comprises the members 102, 103, the member 102 having a pinion 104 thereon and the member 103 having a gear 105 thereon. These members are journaled'about a stud 106 secured to the machine. 107 is a compression-collar for the clutch 101 and is threaded on a threaded extension'108 of the stud 106.L There is a collar 110 splined to the stud 106, as shown at 111, whichforms an end-thrust member of a ball-bearing 112.- A spring 113 is between the collars 110 and 107, the tension of which is arranged to be adjusted by the compression-collar 107 for adjusting thje degree of rfrictional contact in the friction-clutch 101 There is a ball-bearing 114 between the fric-- tion-clutch 101 and the frame. A pinion 115 meshes the gear 105 and is journaled on a stud 116 on the frame and in turn meshes a gear 117 onthe stub 65 of the winding-shaft 65 for operating the latter. The windingshaft is arranged to be clutched to the stub 65 by a clutch v118 and the winding-shaft and stub are respectively journaled in releasable bearings 119 119 inthe frame. The clutch-member 102 forms a brake-member for the friction-clutch 101 for providing retarding action in the winding roll when this is desired. Thus 120 is a brake having a brakeshoe 121 and a lever 122 for operating the same and arranged to force the shoe against the rim of the friction-.member 102.

Gear transmission is effected between the friction-clutches by means of a gear 125 which meshes lwith the-pinion 85 on the clutch-member 84, a gear 126 meshing the gear 125, and a` gear 127 meshing the gear 126 and the pinion 104 on the friction-inember 102. rI`he gears 125 and 127 are respectively journaled on studs 128 and 130 suitably secured to the frame of the machine, the gear 126 being on a shaft 129.

The surface-winding roller is supportedV and driven as follows 135 is a jointed rockerframe com rising the bell-crank member V136 and the linl-member 137, hinged together on a swingingl tie-rod 138, and rocking on the tie-rod 5 which connects the sides of the 'machine-frame. The member 136 comprises the side-arms 139 140 whose outer ends are connected by a tie-rod 141 upon which suitable weights 1.42 are adapted to be supported for normally swinging the surface-winding roller toward the roll being Wound. The member 137 comprises the side-arms 143 144 having bearings 145 146 for the reduced ends 147 of the surface-winding shaft, these reduced ends forming studs received by slots 148 in arms 149 on the machine-frame, the slots preferably being radial of the centerwinding shaft. As the diameter of the roll being wound increases the surface-winding roller is forced outwardly, guided by the slots, against the resistance of the weights 142. .Rotary motion is also communicated to the surface-winding roller 76, which I ac complish by a train of gearing preferably having the same source of power as the gears for the center-winding shaft and referably so arranged that the surface-win ing roller may be continually driven irrespective of the diametersl which the rewinding roll may attain. Thus 151 is a gear secured to the shaft 129 for rotating therewith. l,The gear 151 meshes with a gear 152 journaled on a stud 1'53 secured to the machine-frame and in turn meshes with a gear 154 having a rotary axis coincident with the rocking-'axis of the rocker-frame 135, being journaled on the tierod 5.

The arms 139 and 143 are preferably the gear-supporting arms of the jointed rockerfr'ame. A gearl 155 meshes with the gear 154 and a gear 156 meshes with the gear 155, the gears 155 and 156 being journaled on studs 157 158 secured to the arm 139. Gears 159 and 160 are secured together and journaled on the tierod 138 which forms the articulation between the members of the rockerframe. The gears 159 and 160 rotate together, the gear 159 being meshed by lthe gear 156 and the gear 160meshing with a pinion 162 journaled `on a studv 163 secured to the arm 143. A gear 164 meshes with vthe pinion 162 and is secured to the surfacewinding shaft for operating the latter. In this manner a uniform speed is imparted to the surface-winding roller irrespective of the diameter of the roll being Wound, the respective tubes of the surface-winding roller being sufliciently loose upon the surface-winding shaft to permit turning thereon and exerting` frictional driving contact between the ysurface of the winding roller and the periphery of the roll being wound for exerting differential winding action upon the various narrow-stripped rolls being wound, the washers also acting to maintain the various strip-rolls in separated relation, the center-winding shaft meanwhile acting to collectively wind all of the strip-rolls and erforming the main duty of the winding, eaving the surfacewinding sectional roller to act as an auxiliary surface-Winding roller acting to di'erentially take care of the differences in compactness of the separate strip-rolls, the combined action of the center and surface-winding effect being to compact the several strip-rolls in the winding action.

In operation, the speed of the center-winding shaft is fastest at the beginning of the winding of the roll, as the roll is then of smallest diameter. s the roll increases in diameter its weight also increases thereby requiring reater driving force to drive it, which Wi l partially determine its peripheral speed, its peripheral speed being also determined by the adjustment of the frictionclutch 101 by means of the compression-collar 107. In practice it is necessary to supply greater frictional contact as the diameter of the -rewinding roll increases for maintaining a given peripheral speed. The surfacewinding roller rotates in the direction opposite tothe direction of rotation of the centerwinding arbor, as indicated by the arrows a b, and the speed of the surface-winding tubes is preferably greater than they peripheral speed of the roll being wound so as to selectively crowd the various strips upon the roll being wound, but, While the surfacewindin tubes operate with faster peirpheral speed tIxan the peripheral speed of the roll be ing wound,` their frictional p'ower is preferably riot sufficiently great to substantially overhaul the center-winding shaft. The surface-winding roller acts as a surface-wind- 'iis ing auxiliary to the center-Winding and aids l I erted throughout the bulk of the roll being wound, which is composed of the separated strips. It relieves the tension upon those separated strips, which tension would otherwise be exerted throughout the full length ofl the strips between the drawing roller and the center arbor. It acts intermediately of those points for aidingin drawingthe separated strips about the central arbor, in other words, acts upon the surface of the strips-to the extent to which they have been wound for taking care of that portion of the strips already wound into the roll, and relieves that lportion of pulling stress from the stretches of the strips between the auxiliary surface-winding roller and the drawin rollers and -thereby insures that the tension of all the strips in their stretches between the surface-winding roller and thev drawing rollers shall be substantially equal, thereby preventing undue stress on any one of the separate strips for preventing tearing of the strips.`

,- For driving the drawing rollers and the knife-shafts, I provide the lower drawingroller shaft with a gear 167 which meshes the pinion 85. The upper drawing-roller is driven by frictional contact With the paper and lower roller. There is a second gear r168 on the lower drawing-roller nshaft which -meshes with a pinion 169 journaled on a stud 170 secured to the machine-frame and in turn meshes a gear 171 on the lower knifeshaft, the latter gear in turn meshing with a roll being wound simultaneously gear 17 2'on the upper knife-shaft for causing the knives to rotate in unison.

If desired the separatedstrips may have their ends secured to and be wound about cops 173 separated by washers 174, the cops and washers being firmly secured to the re- Winding shaft 65 by being clamped between a collar 175 and a nut 17 6 threaded on the rewinding shaft.
